First, the overall structure and installation position of the lock knob structure of the vehicle door according to the present invention will be described with reference to FIG. 1.

The vehicle door 10 has a door trim 12 disposed therein, a steel sheet 16 disposed outside, and a guide groove 15 formed between the door trim 12 and the steel sheet 16. A door glass 14 capable of vertically translating movement, and a lock knob 20 disposed on the door trim 12 are provided. The lock knob 20 is fixed on the door trim 12 and is vertically moved through a lock knob bezel 30 having a through hole 32 and a through hole 32 of the lock knob bezel 30. A lock knob rod 22 is provided to translate. The lock knob rod 22 is linked to a fixing device (not shown) for fastening the door 10 to the vehicle body through the connection bar 24. That is, in the state in which the lock knob rod 22 is lifted upward, the fixing device is released and the door 10 can be opened. However, in the state in which the lock knob rod 22 is pressed by pressure, the fixing device is released and the door ( 10) remain fixed to the vehicle body.

The lock knob bezel 30 has a body portion 34 having a through hole 32 formed therein, a head portion 31 connected to an upper end of the body portion 34 and seated on an upper end of the door trim 12. An elastic support member 32 formed on the inner surface of the body portion 34 is provided.

The body portion 34 is provided with an exposed protrusion 35 extending in an upward direction from its outer circumferential surface. The exposed protrusion 35 functions to allow the lock knob bezel 30 to be fixed on the door trim 12 without swinging. That is, the exposed protrusion 35 formed on the upper side in a state where the lower surface of the head 31 is in close contact with the upper end of the door trim 12 may cause the lock knob bezel 30 to escape from the door trim 12 or shake. It can prevent it beforehand.

On the other hand, the body portion 34 can have a tapered shape of the inner circumferential surface thereof from the elastic support member 32. In other words, the inner circumferential surface of the body portion 34 may have a shape that extends in the vertical direction from the elastic support member 32 as a starting point. Under the above structure, when the lock knob rod 22 is fastened through the through hole 32, the elastic support member 32 receives the predetermined pressure by the lock knob rod 22 to maintain the pressed state.

The elastic support member 32 may be formed in a ring type shape, and the lock knob rod 22 moves in close contact with the elastic support member 32 to lock the bezel 30 and the lock knob rod 22. To block out possible noise. The elastic support member 32 may be formed of an ethylene propylene diene (EPDM) material, and the EPDM may be used as a weather strip of a vehicle, various hoses, packing, sealing, and protector member. Since there is an advantage that the impact resistance is strong as a possible material, when used as the elastic support member 32 in the present invention, there is an advantage that the possibility of problems such as wear or deformation resulting from friction with the lock knob rod 22 is significantly reduced.
